SMOOTHING AND POLISHING IRON.

SPECIFICATION forming part of LetterslPatent No. 346,814, dated August3, 1886. Application filed February 11, 1886. Serial No. 191,548. (Nomodel.)

To all whom, it may concern:

Be it known that we, BENJAMIN F. HosTET- TER and IsAAc (1H. GILMORE,citizens of the United States, residing at Oskaloosa, in the county ofMahaska and State of Iowa, have invented certain new and usefulImprovements in Smoothing and Polishing Irons; and we do hereby declarethat the following` is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and ligures of reference markedthereon.

Figure l of the drawings is a longitudinal section of our invention;Fig. 2, a transverse section thereof, and Fig. 3 a horizontal section ofa portion.

In the accompanying drawings, A represents the body or shell of theiron, formed of an outer wall, a, and an inner Wall, b, the top of thebody or shell having a suitable handle, B. This handle is preferablyformed, as shown, inclining upward in a direction toward the front endof theiron, to adapt it to the motion of the iron, which is back andforth, rendering it much easier to the operator.

The body or shell of the iron, consisting of the walls c b, is cast inone piece, a space being left between the two walls for a filling ofplaster-of-paris or any other suitable heat-nonconducting material.

In casting the body orshell the bottom, side walls, and the inner wallof the top are all cast in one piece, the outer wall of the top of theiron being cast separately,and secured in place by screws or any othersuitable fastening. The f outer side walls, a, at their rear ends arecast with L-shaped guides c, to receive a sliding door, C, said doorbeing formed hollow, and containing a filling, d, of plaster-of-paris orother heat-non-conducting material, said door having a suitable knob orthumb-piece, e, for raising it.

It will be noticed that the heatingcore D is introduced through theopening at the rear end of the iron, and also withdrawn in the samemanner, instead of removing the top of the iron, thereby preventing to acertain extent the too rapid escape of heat and the cooling of the iron.

The inner side walls, b, do not extend on the same vertical plane fromtop to bottom of the body or shell A; but at their lower edges the wallsextend at an angle outwardly or in a direction toward the outer sidewalls, a, as shown at f. The object of this is to have the entire innersurface of the face or bottom of the iron exposed to the heat, so thatit will be heated uniformly from the center to the edges of theironing-surfaces.

It is the purpose of the invention to so construct the bottom of theheating-core D that as little of its surface as possible will come incontact with the bottom of the shell or body of the iron, in order toprevent its becoming too hot. To attain this end, the core D is castwith V-shaped ribs g, the apex thereof formed by the angles resting onthe bottom of the body or shell A, thus having only'a slightpointofcoutact of the core with the bottom, and also forming spaces betweenthe ribs for the circulation of the heated air. The air-space h extendsthe entire length of the core D, and is open at its ends, to allow theair to passalong the space and out at the ends, extending up the sidesand over the top of the core, thus keeping up a circulation oi' air andequalizing the temperature of the iron, and preventing burning thegoods.

The rear ends of the heating-core D is cast with a recess, t', toreceive a lifter or other convenient tool, and is formed with holes k,extending into the core some distance on a line between the ribs g. rIheholes k do not extend entirely through the core D, and therefore areclosed at their lower ends, the object lthereof being to insure the coreheating as rapidly at or near its center as at its surface.

The core AD is cast at its 'sides with lugs Z, to prevent the core fromshifting its position centrally to the sides of the body or shell,thereby holding it stationary-and preserving a space for the circulationof the heated air between the sides of the core and the inner sidewalls.

We provide a core-heating sad-iron having all of its sides except theoperating-face packed with non-conducting material. By the angular partf of the side walls we allow the heat to affect the entire working faceor bottom.

By forming the operating-face smooth it will i heat evenly, and bygiving the core the smallest possible bearing upon the bottom we furtherinsure a regular uniform heating of the operating-face.

Having now fully described our invention,

whatwe claim as new, anddesire to secure by Letters Patent, Yis

In a coreheating iron, the combination, with the core thereof, of thebody or shell formed of an outer and an inner wall and a.heat-nonconducting lling between the same, the inner side walls at theirlower edges extending outwardly at an angle and joining the outer side
